Your movement speed increase by 10 as you dash and wind swirls around you, increasing with intensity the longer you run. The next creature you hit with a melee weapon attack must make a Strength saving throw or take 1d4 bludgeoning damage for every 10 feet you moved on your turn (maximum of 6d4), and the creature is knocked away from you 5 feet for every d4 of bludgeoning damage taken. The creature only takes half as much damage on a successful save and is not pushed.

The spell ends if you do not move on your turn or are incapacitated.

Using a Higher-Level Spell Slot. The maximum for d4s increases by 1 for each spell slot level above 2.
